Experts weigh in on obesity policies

Experts on public policy and nutrition share their thoughts about government's role in fighting obesity. "The government is up to its ears in policies that promote obesity," nutrition expert Marion Nestle says. Brian Wansink, director of the Food and Brand Lab at Cornell University, says, "The biggest disservice that public health has ever done to Americans is to make them believe that they and their kids were fat because the schools, the food companies, the fast-food restaurants and the government made them that way."
